Disclosed herein is a surface treatment method of a ceramic powder using microwave plasma in order to enhance flowability. The surface treatment method can be applied to a ceramic powder having a small particle size of 45 &#x3bc;m or less and can significantly enhance flowability while reducing an influence on a particle size compared to a conventional method. Consequently, the ceramic particles surface-treated by the above-described surface treatment method can be formed to have a smooth and dense coating film without pores during spray coating.

Surface treatment method of ceramic powder using microwave plasma for enhancing flowability

The present invention provides a hybrid reforming system for producing syngas through a reforming reaction between carbon dioxide plasma and a hydrocarbon material, the system comprising: a carbon dioxide feeder () which feeds carbon dioxide; a hydrocarbon material feeder () which feeds the hydrocarbon material; a plasma reformer () which respectively receives carbon dioxide and the hydrocarbon material from the carbon dioxide feeder () and the hydrocarbon material feeder (), and produces primary syngas through a reforming reaction while producing the carbon dioxide plasma using electromagnetic waves; a wet carbon-refining device () which is arranged at a gas exhaust end of the plasma reformer () and filters and refines carbon contained in the primary syngas; and a catalyst dry-reformer () which is arranged at a gas exhaust end of the wet carbon-refining device () and produces secondary syngas by making the refined syngas undergo a catalyst dry-reforming reaction.

Hybrid reforming system using carbon dioxide plasma and catalyst

The present invention discloses a plasma dry reforming apparatus for producing synthetic gas, main components of which are hydrogen and carbon monoxide, by reforming methane and carbon dioxide injected in plasma, the apparatus comprising: a plasma reformerwhich produces carbon dioxide plasma by making carbon dioxide supplied therein into plasma, ignites plasma flame by supplying hydrocarbon to the produced dioxide plasma, and produces synthetic gas by supplying methane to the plasma flame.
